Off-design operation reorganizes centrifugal-pump pressure pulsations through interaction between the rotating impeller discharge and the stationary volute. To clarify how the non-uniform impeller-outlet pressure field is concentrated and modulated in the volute, unsteady computational fluid dynamics was performed at 0...

Inline pumps are widely used in space-constrained fluid transport systems, where energy efficiency and operational stability directly affect system safety and economy. The elbow-shaped inlet of a vertical inline pump can induce pronounced non-uniform inflow and alter the impeller inlet conditions. This study investigat...

To clarify the effects of splitter blades on hydraulic performance and internal energy dissipation in a double-suction pump as turbine (PAT), full-passage CFD models of a PAT and a PAT with splitter blades were established and experimentally validated. Same-flow-rate cross-comparisons at the BEP flow rates of the confi...
